44. The expert from India introduced GRSG-129-23, requesting guidance on the formulation of a proposal on a new UN GTR under the 1998 Agreement for fire protection systems in the occupant compartment of internal combustion engine buses, based on the methodology of the Indian standard. At the same time, he proposed that the standard from his country on this subject - Fire Detection and Alarm System (FDAS) and Fire Detection and Suppression Systems (FDSS) for Buses - be added to the compendium of Candidate of the 1998 Agreement (GRSG-129-24). He explained that this initiative was a follow-up of accidents originated by occupant compartments and from outside. The expert from OICA argued that there are different compartment materials. The expert from Canada stated that he was unaware of any victims of bus fires in his country and therefore had no issue with moving forward on a fire suppression system. Finally, the GRSG Chair stated that time for reflection was needed and that this proposal would be in the highlights of the Chair at the June 2025 session of WP.29. At the same time, the secretariat was requested to keep GRSG-129-23 and GRSG-129-24 in the agenda, as references.
